Hi slimpikins5, your concern of ICEpower-based amps sounding sub-musical has some merits, if mostly from a historical point of view....
Examples of such unsatisfying amps could be found easily in some older class D amps such as the Wyred4Sound that I have heard at RMAF until about five years ago (They might have changed since then), early Red Dragon 500, and stock Rowland M201 and M501 (that is without being connected to the optional PC-1 PFC external rectifier).
This however does not imply that all ICEpower based amps are inherently less than musical... In fact, even some now elderly amps that I have had in my system such as the Rowland M312 stereo and the Bel Canto REF1000M were authentic musical marvels, particularly for the time.
I have heard only good third party reports about recent ICEpower implementations... ’Tis worth keeping an open mind about ICEpoweer amps designed in the last three to four years. particularly if they are not simply boxes containing more or less basic ICEpower modules and little else.
ICEpower modules are very flexible... A manufacturer can use them all by themselves to create an entry level amp, or can use them as building blocks in the design of amps of any increasing level of sophistication.
Saluti, Guido
